Coamoebas of polynomials supported on circuits

Jens Forsgård

Published 2016-01-20Version 1

We study coamoebas of polynomials supported on circuits. Our results include an explicit description of the space of coamoebas, a relation between connected components of the coamoeba complement and critical points of the polynomial, an upper bound on the area of a planar coamoeba, and a recovered bound on the number of positive solutions of a fewnomial system.

Comments: To appear in the memorial volume of Mikael Passare
